Cognitive Performance & Health

Meet the Cognitive Performance & Health Team

Dr. James Seberger, M.D. Ph.D.


Dr. Seberger obtained both his Ph.D. and M.D. from the University of Nebraska Medical Center, completing his Ph.D. in biochemistry and molecular biology in 1999 and his M.D. in 2003. He then moved to Wichita, KS, where he finished his residency in Family Medicine in 2003. He opened his private practice in 2012 and continues to practice Emergency Medicine in the hospital setting as well.


He works with his wife, Veronica, at Cognitive Performance & Health, where he is a family medicine practitioner. His family medicine practice employs many types of modalities: medicine, vitamin supplementation, and neurofeedback. “I try to have as many tools in my toolbox as I can. Sometimes patients are maxed out on different types of medicine and need additional means to control their blood pressure and get their glucose down.”


“I try to identify the root of the problem so I can directly address it. My goal is to recalibrate the patient, so to speak, and stop any decline that may be occurring. From there, we focus on improving their health to really help them feel and perform better.”
